规模化开发者体验：我们如何在大型 monorepo 中改进 Android Studio

Introduction

引言

Long integrated development environment (IDE) sync/indexing times can quietly erode developer productivity, making code navigation sluggish, spiking memory usage, and slowing down Jetpack Compose preview updates, turning the IDE into a bottleneck rather than a helpful tool. For Android engineers working in a large monorepo, this was a daily reality. In this post, we will share how we built a custom Focus plugin that dramatically reduced Android Studio sync times by leveraging our existing investments, such as the Gradle-to-Bazel migration workflow.

长时间的集成开发环境 (IDE) 同步/索引时间会悄无声息地侵蚀开发者生产力，导致代码导航迟缓、内存使用激增，并减慢 Jetpack Compose 预览更新，将 IDE 变成瓶颈而非有用的工具。对于在大型 monorepo 中工作的 Android 工程师来说，这是日常现实。在本文中，我们将分享如何构建一个自定义 Focus 插件，通过利用我们现有的投资（如 Gradle 到 Bazel 的迁移工作流）大幅减少 Android Studio 同步时间。

Our Android monorepo at scale

我们大规模的 Android monorepo

The Grab passenger Android (PAX) repository contains roughly 2,000 Android modules and 11,000,000 lines of code. As the repository grows year over year, a natural consequence of scaling our superapp, which combines ride-hailing, food delivery, payments, and more into a single application, is the increase in time required to build and sync the project.

Grab 乘客 Android (PAX) 仓库包含大约 2,000 个 Android 模块和 11,000,000 行代码。随着仓库逐年增长，这是我们 superapp 扩展的自然结果，该 superapp 将 ride-hailing、food delivery、payments 等结合到一个单一应用程序中，导致构建和同步项目所需的时间增加。

What makes this growth especially pronounced today is the shift in how code gets written. Development assisted by artificial intelligence (AI) has enabled engineers to produce more code faster than before. At the same time, non-engineering personnel such as designers, product managers, and other non-technical contributors have started making changes to low-risk features under engineering provision. Together, these two forces are pushing the codebase to grow at its fastest rate ever, which in turn compounds the pressure on every developer’s IDE and build tooling to keep up.

如今这种增长尤为明显的原因是代码编写方式的转变。由人工智能 (AI) 辅助的开发使工程师能够以前所未有的速度产生更多代码。同时，非工程人员如设计师、产品经理和其他非技术...
